Description

La présente invention concerne un mousqueton à combinaison à mécanisme plan du type selon le préambule de la revendication 1.The present invention relates to a planar mechanism combination carabiner of the type according to the preamble of claim 1.

Il est connu des cadenas à combinaison classiques, tels que celui montré par exemple à la figure 5, qui comprend une pluralité de molettes D montées de façon pivotante sur un arceau S, chaque molette D étant perpendiculaire à un axe A d'une branche de l'arceau S, et qui peuvent présenter certains inconvénients comme suit.

  • 1°) Quand on désire ouvrir un tel cadenas, il faut tirer vers le haut l'extrémité de blocage de l'arceau S puis la faire tourner dans le sens R autour de l'axe A pour retirer le cadenas d'une attache montée par exemple sur le cadre d'une porte, ce qui fait que sa manoeuvre est difficile.
  • 2°) Toutes les molettes D sont perpendiculaires à l'arceau S et il n'est donc pas possible de prévoir un boîtier peu épais, ce qui exige en outre un espace important pour sa manipulation et son stockage.
Conventional combination padlocks are known, such as that shown for example in FIG. 5, which comprises a plurality of knobs D pivotally mounted on a hoop S, each knurl D being perpendicular to an axis A of a branch of the arch S, and which can have certain drawbacks as follows.
  • 1 °) When you wish to open such a padlock, you must pull upwards the locking end of the arch S then rotate it in the direction R around the axis A to remove the padlock from a mounted clip for example on the frame of a door, which makes its operation difficult.
  • 2) All the knobs D are perpendicular to the arch S and it is therefore not possible to provide a thin case, which also requires a large space for its handling and storage.

Le présent inventeur a constaté ces inconvénients et a inventé le présent mousqueton à combinaison à mécanisme plan pour surmonter les inconvénients susmentionnés.The present inventor has noted these drawbacks and has invented the present planar mechanism combination carabiner to overcome the above-mentioned drawbacks.

The opening end portion 112 comprises an inclined surface going decreasing towards the outside in a direction opposite to the central curved portion 110. The closing tab 12 which has the general shape of an "r" and which is placed against the second longitudinal side 1d comprises a portion of lower branch 121 comprising a pivot hole 124 pivotally mounted on a pivot 125 formed on the first cover 1, and an upper vertical arm portion 122 comprising an inclined surface 122a formed at its outermost end of this upper arm portion 122 and decreasing inwards in the direction of the curved portion 110 of the hook 11, a horizontal arm portion 123 oriented inwards in the direction of the first longitudinal side 1c of the p replace cover 1, and a return spring 126 normally recalling the tongue 12 outwards to allow the outermost end 122a of the upper arm portion 122 to come into engagement with the end portion d opening 112.

Une surface externe de la languette 12 comprend une surface ondulée 120 facilitant la pression exercée par le doigt de l'utilisateur. La languette 12 est dans le même plan que le crochet fixe 11.An external surface of the tongue 12 comprises a corrugated surface 120 facilitating the pressure exerted by the user's finger. The tongue 12 is in the same plane as the fixed hook 11.

Chaque molette 3 dont le diamètre est parallèle au couvercle 1 ou 2 comprend un trou central 31 destiné au montage pivotant de la molette sur l'arbre 13 du premier couvercle 1, une pluralité de trous 32 constitués dans une surface de la molette et disposés radialement autour du trou central 31 pour venir en engagement fonctionnel avec plusieurs plots 14, dix chiffres 33 formés radialement sur la surface de la molette, et une pluralité de plots 34 formés radialement sur l'autre surface de la molette pour venir en engagement fonctionnel avec une pluralité d'évidements 44 dans un manchon 4.Each wheel 3 whose diameter is parallel to the cover 1 or 2 comprises a central hole 31 intended for the pivoting mounting of the wheel on the shaft 13 of the first cover 1, a plurality of holes 32 formed in a surface of the wheel and arranged radially around the central hole 31 to come into functional engagement with several studs 14, ten digits 33 formed radially on the surface of the wheel, and a plurality of studs 34 formed radially on the other surface of the wheel to come into functional engagement with a plurality of recesses 44 in a sleeve 4.

Chaque manchon 4 comprend : un trou central 41 destiné au montage pivotant du manchon 4 sur l'arbre 13 de façon à se disposer sur chaque molette 3, une poche centrale à ressort 42 pour retenir un ressort 45 maintenu entre le second couvercle 2 et la poche 42 de façon à accoupler élastiquement en rotation chaque manchon 4 avec chaque molette 3, une encoche 43 constituée dans le manchon pour communiquer avec la poche à ressort 42 et définissant deux surfaces inclinées 430 divergeant vers l'extérieur, et une pluralité d'évidements 44 formés dans une surface opposée à l'encoche 43 et destinés à venir en engagement fonctionnel avec les plots 34 de la molette 3.Each sleeve 4 comprises: a central hole 41 intended for the pivoting mounting of the sleeve 4 on the shaft 13 so as to be arranged on each wheel 3, a central spring pocket 42 for retaining a spring 45 held between the second cover 2 and the pocket 42 so as to elastically couple in rotation each sleeve 4 with each wheel 3, a notch 43 formed in the sleeve to communicate with the spring pocket 42 and defining two inclined surfaces 430 diverging towards the outside, and a plurality of recesses 44 formed in a surface opposite the notch 43 and intended to come into functional engagement with the studs 34 of the thumb wheel 3.

Le verrou coulissant élastique 5 qui est monté de façon coulissante contre un premier côté longitudinal 1c du premier couvercle 1 comprend : une pluralité de trous à manchon 51 constitués dans le verrou et dans lesquels s'engagent fonctionnellement les manchons 4, un ressort de rappel 52 formé sur une portion inférieure du verrou maintenu dans une poche à ressort 21 formée dans le second couvercle 2 contre le second côté transversal 1b du premier couvercle 1 pour ramener normalement le verrou 5 vers le bas, et un prolongement supérieur 53 formé sur une portion supérieure du verrou à l'opposé du ressort 52 pour arrêter fonctionnellement la portion de bras horizontale 123 de la languette de fermeture 12 quand on ferme le dispositif de la présente invention. Chaque trou à manchon qui a la forme générale d'une ellipse 51 comprend une portion de languette 50 allant en diminuant vers le bas à partir de la périphérie supérieure du trou 51 et définissant deux surfaces inclinées 501 convergeant vers le bas pour venir coopérer fonctionnellement avec les deux surfaces inclinées 430 d'une encoche 43 du manchon 4 comme montré à la figure 2A, et un rebord courbe et concave 502 intersectant latéralement les deux surfaces inclinées 501 et venant coopérer fonctionnellement avec la circonférence du manchon comme montré à la figure 2. La distance entre le rebord courbe 502 et la périphérie inférieure du trou 51 est de façon générale égale au diamètre du manchon. Ceci signifie que le diamètre du manchon est égal à la longueur d'un axe long D moins la longueur longitudinale T de la portion de languette 50, comme montré à la figure 1. La largeur de l'axe court du trou à manchon 51 est légèrement plus importante que le diamètre du manchon. Le trou le plus en bas 51a peut être évidé sur un côté du verrou 5 pour former directement un ressort 52 sur le verrou.The elastic sliding latch 5 which is slidably mounted against a first longitudinal side 1c of the first cover 1 comprises: a plurality of sleeve holes 51 formed in the latch and in which the sleeves 4 engage functionally, a return spring 52 formed on a lower portion of the lock held in a spring pocket 21 formed in the second cover 2 against the second transverse side 1b of the first cover 1 to normally bring the lock 5 down, and an upper extension 53 formed on an upper portion of the latch opposite the spring 52 to functionally stop the horizontal arm portion 123 of the closing tab 12 when the device of the present invention is closed. Each sleeve hole which has the general shape of an ellipse 51 includes a tongue portion 50 which tapers downwards from the upper periphery of the hole 51 and defines two inclined surfaces 501 converging downwards to cooperate functionally with the two inclined surfaces 430 of a notch 43 of the sleeve 4 as shown in FIG. 2A, and a curved and concave edge 502 laterally intersecting the two inclined surfaces 501 and coming to cooperate functionally with the circumference of the sleeve as shown in FIG. 2. The distance between the curved edge 502 and the lower periphery of the hole 51 is generally equal to the diameter of the sleeve. This means that the diameter of the sleeve is equal to the length of a long axis D minus the longitudinal length T of the tongue portion 50, as shown in Figure 1. The width of the short axis of the sleeve hole 51 is slightly more important than the diameter of the sleeve. The lowest hole 51a can be hollowed out on one side of the latch 5 to directly form a spring 52 on the latch.

Quand on ferme le dispositif de la présente invention, on peut faire tourner la molette 3 pour entraîner le manchon 4 et permettre aux deux surfaces inclinées 430 de l'encoche 43 de pousser les deux surfaces inclinées 501 et la portion de languette 50 du verrou 5 de façon à soulever le verrou, le prolongement supérieur 53 du verrou 5 arrêtant la portion de bras horizontale 123, ce qui fait que la languette 12 ne peut pas être pressée vers l'intérieur et ouvrir le mousqueton, tandis que le ressort 126 ramène la languette 12 vers l'extérieur pour permettre à la surface inclinée 122a de la portion de bras verticale 122 de se placer sur la surface inclinée 113 de l'extrémité d'ouverture du crochet 11, ce qui détermine une position de blocage de la languette 12 sans mouvement vers l'intérieur ou vers l'extérieur.When the device of the present invention is closed, the dial 3 can be turned to drive the sleeve 4 and allow the two inclined surfaces 430 of the notch 43 to push the two inclined surfaces 501 and the tongue portion 50 of the latch 5 so as to raise the bolt, the upper extension 53 of the bolt 5 stopping the horizontal arm portion 123, which means that the tongue 12 cannot be pressed inwards and open the carabiner, while the spring 126 brings the tongue 12 outwards to allow the inclined surface 122a of the vertical arm portion 122 to be placed on the inclined surface 113 of the opening end of the hook 11, which determines a locking position of the tongue 12 without movement inwards or outwards.

Quand on ouvre le dispositif de la présente invention en faisant tourner les molettes 3 vers les combinaisons d'ouverture, la portion de languette 50 du verrou 5 est tirée vers le bas de manière à être engagée dans l'encoche 43 du manchon 4 par le ressort de rappel 52 et abaisser le prolongement 53 en cessant d'arrêter la portion de bras horizontale 123, suite à quoi, quand on presse la languette 12, la portion de bras verticale 122 s'ouvre par rapport au crochet 11 et ouvre le mousqueton de cette invention.When the device of the present invention is opened by rotating the knobs 3 towards the opening combinations, the tongue portion 50 of the latch 5 is pulled down so as to be engaged in the notch 43 of the sleeve 4 by the return spring 52 and lower the extension 53 by ceasing to stop the horizontal arm portion 123, after which, when the tongue 12 is pressed, the vertical arm portion 122 opens relative to the hook 11 and opens the carabiner of this invention.

Pour modifier une combinaison du mousqueton de la présente invention on presse la languette 12 pour permettre à la portion de bras horizontale 123 d'appliquer une pression sur le verrou 5 et d'engager la portion de languette 50 dans l'encoche 43 du manchon, ce qui fait que l'on peut faire tourner les molettes 3 sans qu'elles soient accouplées aux manchons 4, pour établir une nouvelle combinaison.To modify a combination of the carabiner of the present invention, the tongue 12 is pressed to allow the horizontal arm portion 123 to apply pressure on the latch 5 and to engage the tongue portion 50 in the notch 43 of the sleeve, which means that the knobs 3 can be turned without being coupled to sleeves 4, to establish a new combination.

Le mousqueton de la présente invention est supérieur au cadenas à combinaison classique et présente les avantages suivants:

  • 1°) Tous les éléments sont généralement de forme plate et mince afin d'économiser de la place.
  • 2°) La languette 12 est actionnée dans un plan pour ouvrir et fermer le mousqueton en vue de faciliter son fonctionnement.
The carabiner of the present invention is superior to the conventional combination padlock and has the following advantages:
  • 1 °) All the elements are generally flat and thin in order to save space.
  • 2) The tongue 12 is actuated in a plane to open and close the carabiner in order to facilitate its operation.
